I have a p-ch mosfet with the gate being driven by a microcontroller at 1.2Khz 50% duty cycle between 3v and 0v. The mosfet threshold voltage is achieved.
But I don't understand why the waveform is not reaching 0V. The scope is probed between the source (Va) and the drain (GND) of the mosfet. I would assume during each "ON" cycle of the FET the waveform would reach 0V.
Additionally, why is the waveform not between 10V and 0V? Instead its between 5.8V and about 3V.
